Multi-point combustion bidirectional rotary kiln

Abstract

The invention discloses a multi-point combustion bidirectional rotary kiln. The multi-point combustion bidirectional rotary kiln comprises a base, a driving device, a first kiln body, an adjusting assembly, a driving assembly and a bearing assembly; the driving device is fixedly arranged at the right side of the top end of the base; the first kiln body is arranged at the top end of the inner side of the driving device and can rotate around the axis of the first kiln body; the adjusting assembly is fixedly arranged at the middle position of the top end of the base; the driving assembly is arranged at the left side of the middle of the top end of the base; and the bearing assembly is arranged at the left side of the top end of the base. According to the multi-point combustion bidirectional rotary kiln, different process adjustments can be conducted on the requirements of materials at different positions through the double-section kiln body manner, the steady-state time of fluid can be shortened through strip-shaped protrusions on the inner wall of the kiln body, and the baffling gradient effect is improved; and the accident occurrence risk is reduced, and the situation of material retention caused by the inner wall protrusions is avoided.

Description

technical field [0001] The invention relates to the technical field of rotary kilns, in particular to a multi-point combustion bidirectional rotary kiln. Background technique [0002] Rotary bed kiln refers to rotary calcining kiln (commonly known as rotary kiln), similar in shape to rotary bed, also called rotary bed kiln, which belongs to building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials processed Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidation roasting of chromium and nickel iron ore ; The refractory material plant roasts high-alumina bauxite ore and the aluminum plant roasts clinker and aluminum hydroxide; ...
